AMSTERDAM — Following the report of results from a randomized trial in which a topically applied Janus kinase (JAK) inhibitor was highly active in
“Ruxolitinib cream may be a novel approach to address an unmet medical need in the treatment of milder HS for which there are no currently approved treatments,” reported Martina L. Porter, MD, assistant professor of dermatology, Harvard Medical School, and Beth Israel Deaconess Medical Center, both in Boston, Massachusetts.
In the earlier 16-week, double-blind, randomized period of this phase 2b study, 69 adults with mild to moderate HS were randomized to 1.5% ruxolitinib cream or vehicle, applied twice daily for 16 weeks. The new results are from the open-label extension period, where those on the vehicle were crossed over to topical ruxolitinib and treatment was continued for another 16 weeks.
Over 80% Meet Primary Endpoint at 32 Weeks
Entry criteria for the study included Hurley stage I or II HS with no draining tunnels. Hurley stage III patients were not eligible. Patients had to have an abscess or inflammatory nodule (AN) count of 3 lesions concentrated in a single anatomic area or up to 10 lesions if disseminated. The median AN count of those enrolled was 5.4.
In the randomized portion of the study and in the open-label extension, the recommendation for application was to apply the medication to nodules and a 1-cm area of surrounding skin. As-needed treatment was only recommended in the extension portion of the study and rescue medication was not allowed.
The goal of the open-label extension was to evaluate how long the improvements were sustained, according to Dr. Porter, who presented the results at the 2024 European Academy of Dermatology and Venereology (EADV) meeting.
The primary endpoints of AN50, signaling at least a 50% reduction in AN count from baseline, among those initially randomized to ruxolitinib cream climbed slightly from 79.2% at the end of 16 weeks to 81.0% at the end of 32 weeks.
This shows that the benefits recorded in the randomized phase of the trial were sustained during the open-label extension, Dr. Porter said.
For those randomized to vehicle, there was a substantial response of 56.3% for AN50 during the randomized portion of the study, but catchup in the vehicle group to those on active therapy occurred rapidly over the open-label extension. By the end of 32 weeks, the score among the crossover patients slightly exceeded that of those on continuous therapy (88.5% vs 81.0%).
AN75 responses at week 32 were 66.7% and 61.5% in the continuous arm and crossover arm, respectively. The proportion of patients reaching an AN90 or AN100 response, meaning clear or almost clear, were 19% and 38.5%, in continuous treatment and crossover arms, respectively.
One of the secondary endpoints was the HS Clinical Response 50, indicating at least a 50% reduction in the AN count with no increase in abscesses or draining fistulae. At 32 weeks, the proportions of patients who met this endpoint were 81.0% and 88.5% in the continuous treatment and crossover arms, respectively.
The mean reduction in International HS Severity Scoring System scores from baseline were 4.1 and 4.5 in the continuous treatment and crossover arms, respectively.
Patients in the Study Mostly Women, 42% Black Individuals
Most (94%) of the participants were women; about 45% and 42% were White and Black individuals, respectively. Most of the remaining patients were Asian individuals. The median age at entry was 29 years, and the mean body mass index was approximately 34 kg/m2. A substantial proportion of patients had systemic comorbidities, according to Dr. Porter, who noted that about 25% had anxiety, depression, or both.
“This phenotype — a high proportion of women with nodules but no draining tunnels and a substantial number of comorbidities — is one we often see in patients with mild HS,” Dr. Porter said.
The safety and tolerability profile of ruxolitinib cream was quite good, according to Dr. Porter, who noted that there were fewer treatment-related adverse events in the open-label extension. Overall, the number of treatment-related adverse events (3.6%), including application site reactions leading to discontinuation (1.8%) was low.
Although there is a growing list of therapies now approved for HS, Dr. Porter emphasized that all have been developed for moderate to severe disease. She suggested that there is a sizable group of patients with mild disease for whom such therapies as biologics might not be warranted even if symptom relief is needed.
Given this unmet need, she said phase 3 trials are warranted to confirm the benefits and the safety of a topical therapy that can be used as needed to control intermittent HS flares.
Asked to comment, the lead author of a recently published review article on the “evolving treatment landscape” of HS, James G. Krueger, MD, professor in clinical investigation at Rockefeller University, New York City, agreed that there is an unmet need for effective and safe therapies in milder HS.
“I agree with the premise,” said Dr. Krueger, indicating that phase 3 data will be essential to confirm the promise of this approach. Dr. Krueger, who did not hear the results presented at the EADV meeting, listed several JAK inhibitors in his review that have shown promising efficacy as oral agents and support JAK signaling as a target of HS treatment.
Topical ruxolitinib (Opzelura) is currently approved in the United States for treating nonsegmental vitiligo in patients aged ≥ 12 years and for mild to moderate atopic dermatitis in patients aged ≥ 12 years. In Europe, it is approved for treatment of nonsegmental vitiligo with facial involvement in patients aged ≥ 12 years.
Dr. Porter reported no potential conflicts of interest. Dr. Krueger reported financial relationships with more than 25 pharmaceutical companies not including Incyte, which is developing ruxolitinib cream.
